The document discusses the manufacturing process of General Tyres. It describes the raw materials used, which include natural rubber, synthetic rubber, and carbon. The manufacturing process involves several steps: banbury blending mixes the raw materials; milling shapes the rubber sheets; extruding and calendering thin the sheets and make components; components are assembled into green tires; curing forms the tires in a mold; finishing and inspection check quality; and finally, packing wraps the finished tires.

3. GENERAL TYRES
• The General Tyres is the largest tyre
manufacturer in the country producing tyres .
• Initial production capacity around 2,000,000
tyres per annum.

4. RAW MATERIALS
• Natural rubber
• Synthetic rubber
• Carbon

5. MANUFACTURING PROCESS
• Banbury Blending
• Milling
• Extruding and Calendering
• Component and Assembly
• Curing
• Finishing and Inspection

6. BANBURY BLENDING
• In this process natural rubber and synthetic is
blended with some specific chemicals to
create a homogenous rubber material.

7. MILLING
• In this process shaping of the rubber takes
place as the rubber sheet comes out from the
banbury mixer is not that perfect.

9. EXTRUDING AND CALENDERING
• Extruding is a very important step as it
converts the thick and heavy rubber sheets
into thin rubber sheets.
• Many of the components are made by this
process such as Thread .

10. • Calendering is the process similar to
sandwiching as it sandwich the thin and sharp
steel wire between the two thin layer of
rubber sheet.
• This process produces the steel belt which is
required in the radial car tyres.

11. COMPONENT AND ASSEMBLY
• At this stage all the tyre components are
assembled together to make a “Green Tyre”
with the help of assembling machine

13. CURING
• This is the process where the Green tyre is
cured in a Dom shape machine having mould
in its inside part at both upper and lower end.

16. FINISHING AND INSPECTION
• Inspection is the last stage or process of tyre
manufacturing which is very important.
• It includes 2 types of inspection:-
1. Manual inspection
2. Weight balancing

17. PACKING
• After inspection the automatic wrapping
machine wrap the in an efficient way to
protect it from sunlight, dust and other
foreign materials
